I worked on Videotex systems in Holland (and basically deprecated it in 2001). At the time it was the profitable part of the ISP it was part of, largely due to the "pink" services it offered via paid dial-in numbers (0.25 Eurocents per minute). Later a web version of Videotex was created which basically emulated the Videotex screen in a http frame. Its services were quickly taken over by the Internet.
